The StressTel T-Mike Basic is a compact, easy-to-use, rugged thickness gauge. T-Mike B set-up is fast and easy; the operator simply selects from five preset materials - steel, aluminum, stainless steel, cast iron, and plexiglass - auto-calibrates, and starts testing. A custom material can also be added by connecting the T-Mike B to a T-Mike E thickness gauge or to your computer.
